The given system of equations represent a single line with positive slope. So option C is correct.
<u>SOLUTION:
</u>
Given system of equations are

Now, if we observe,
multiplying the
equation with 2 results in
equation.
which means the two line equations represents the same line.
Now, let us find the slope of line, 
So, the line has a positive slope.
Answer: 158 as area and perimeter 62
Step-by-step explanation:
Total numbers of whole number that has a sum of 12.
1. 11 + 1 = 12
2. 10 + 2 = 12
3. 9 + 3 = 12
4. 8 + 4 = 12
5. 7 + 5 = 12
6. 6 + 6 = 12
7. 12 + 0= 12
so there are 7 pairs of whole numbers being added that have a sum of 12
Answer:
5.5, 9.5
Step-by-step explanation:
Let x and y be the numbers
x+y = 15
x-y = 4
Add the two equations together to eliminate y
x+y = 15
x-y = 4
------------------
2x = 19
Divide by 2
2x/2 =19/2
x = 9.5
Now find y
x+y = 15
9.5+y = 15
Subtract 9.5
x = 15-9.5
x =5.5
